Nearly 4,000 blood samples from rabbits across Australia help explain the spread of RHDV2
Early summer can result in more sightings of rabbits, especially young ones born since breeding that was stimulated by spring rainfall. The RHDV1-K5 virus has been approved for release but it doesn’t kill young rabbits – it actually provides them with life-long immunity. So now is not the time for a planned K5 release. Instead, […]
The Centre for Invasive Species Solutions (CISS) hopes to register RHDV2 as a biological rabbit control by 2023. The form of rabbit calicivirus appeared in Australia from overseas in 2015, just ahead of the controlled release of calicivirus RHDV1-K5 in 2017. Since then, RHDV2 has been responsible for the death of nearly half the rabbits […]
The RHDV1-K5 team from the Centre for Invasive Species (CISS) has won a National Biosecurity Award for work in the 2017 release and monitoring of the rabbit control virus. When accepting the Award, the Centre for Invasive Species Solutions noted it was a strong cooperative endeavour between the Australian Government, NSW Department of Primary Industries, […]
Following the arrival of RHDV2, European wild rabbit numbers dropped to around 20% of the average over the preceding ten years, according to recently published survey data. The results come from two long-term monitoring sites in South Australia, in the Flinders Ranges and at Turretfield. If the two sites are representative of other areas and […]
A strain of calici virus (RHDV2) first found in eastern Australia in 2015 has now been detected in Western Australia. For more information see the WA DAF media release.
Hugh McGregor is planning to study how cats and foxes respond to the arrival of RHDV2 at the Arid recovery research site at Roxby Downs, in terms of their numbers and diet. For more information see the Arid Recovery News.
RHDV1 has been used as a bio-agent for rabbit control in Australia since 1996. A new virus, RHDV2, has now been found in NSW, Victoria and SA. For more information see the Update from the Invasive Animals CRC.
